You have to take into consideration the engine/class and track surface. If you’re running tag or shifter and the track isn’t too smooth you should be fine with that amount of time. But if you’re running something lower horsepower like lo206 and the track is very smooth, probably not enough time to get full potential of them.
In general lo206 by lap 4 or 5 my kart is fine. Tag lap 2. That’s what I’ve found. So if you scuffed them in practice you should be fine.
